Application filed December 30, 1925. Serial No. 78,383.

' This invention relates to certain new and useful improvements inroofing shingles in which theshingles that are .separately formed areinterengaged and laid in a manner that none of the exposed edges of theshingles will-turn up or curl.

A further object of the invention isto provide a roofing shingle whereinthe shingles for the roof are interengaged with the lower side edges ofthe shingle exposed and return-bent to underlie the face of the shingleto provide a wind, rain and snow-tight joint;

With the above general objects in view and others that will appear asthe nature of the invention is better understood, the same consists ofthe novel form, combination and arrangement of parts hereinafter morefully described, shown in the accompanying drawing and claimed. I

In the drawing, wherein like reference characters designate like partsthroughout the several views, a

Figure 1 is atop plan view showing a plurality of shingles constructedin accordance with the present invention with the shingles interengagingand laid in their com leted form,

Figure 2 is a vertical cross-sectional view taken on line 2--2 of Fig.1,

Figure 3 is a detail sectional view taken on line 3-3 of Fig. 1,'

Figure 4 is a developed plan view of one of the shingles, and Figure 5is a plan View showing the shingle with its interenga-ging portionofolded ,intoo erative position.

In t e acompanying drawing, wherein for pur oses of illustration, thereis shown the pre erred emobdimen't of the invention, the

reference numeral 1 designates a shingle,

preferably formed of any water-proof material desired and from a sheethaving the out-j line of a rectangle as well as including upper edges 2and 3 and lower edges 4 and 5. The opposite corners of the shingle 1between the upper and lower sides thereof are cut away .on parallellines as at 6 which side edges abut adjacent shingles when laid as shownin Fig. 1.

The apex or lower corner of the lower side edges 4 and 5 is in the formof a spear" head 7 that is fashioned by cutting away the side edges 4and 5 as at 8 to provide rear shoulders 9 on the spear head 7. The sideand 10 also providing slats 12 ,foldable upon I I the line 13 as shownin Figs. 4 and 5.

In assembling or interengaging the several shingles for the roof, thespear head- 7 is folded upon the line 14 shown in Fig. 4 with the neckfor the spear head connecting the latter to the body of the shingle 1engaging the shoulders 11 upon adjacent edges 6 of a pair of cooperatingshingles. The fipear head 7 is first inserted under the shoulers 11 andthen it is anchored at 15 to the roof member 16 in superposed relationtothe body portion of a lower shingle as shown in Fig. 2, and said shingleis then laid in a fiat position so that it overlies contacting portionsof adjacent shingles ositioned therebeneath with the exposed aces of thelaid shingles being substantially of diamondv shaped configuration. Theupper portion of j the shingle is secured as at 17 to the roofing memberwhile superposed shingles overlie all of the fastening elements. Theslats 12 being. turned inwardly as shown in Figs. 1 and 5 provide a moreintimate contact between the exposed edges of a shingle and f the faceof a shingle therebeneath to give an exceptionally close and tightcontact or engagement between the shingles. It is to be understood thatthe opposite finished edges of the roof may be formed of sections ofshingles to. effect the complete covering of the roofing member. 7

While there is herein shown and described the preferred embodiment ofthe present invention, it is. nevertheless .to be-understood that minornges may be made therein without departing from the spirit and scope ofthe invention as claimed. I

What is claimed is A roofing shingle comprising a body formed from arectangular sheet with triangular portions removed from diametricallyfop osed corners thereof to provide the s 1 ng e with straight parallelside edges adapted to abut similar edges of similar adjoining shinglw,with a pair of similar notches formed in the lower edges of the sheettorovide transversely alignedright aliigular s ouldersat the lower ends ofsaid s1 e edges, and with a further pair of notches formed in the loweredges ,of the sheet to said tab and slate being adapted to be unform anarrow head tab of the lower corner der-turned for the inter-enga ementand portion of the shingle body having transfastening of a plurali ofthe s ingles, subversely aligned shoulders at its inner upper stantiallyas -descri 5 end, and a slat between each shoulder of the In testimonywhereof I aflix my signature.
